摘要

To meet the growing need for new therapies for major depressive disorder (MDD) and treatment-resistant depression (TRD), there has been renewed interest in the potential antidepressant activity of classic psychedelics, such as psilocybin and N,N-dimethyltryptamine. In several randomized controlled trials, psilocybin with adjunctive psychotherapy reduced the symptoms of TRD and MDD and was generally well tolerated, although longer-term data are lacking. The design of trials with psychoactive compounds requires optimisation to overcome the challenges of functional unblinding and expectancy; changing global perspectives and legislation may further support and improve investigation of classic psychedelics for the treatment of depressive disorders.
